If you have Diplomacy and  just updated today a new beta patch just made every mod obsolete. Also the mods you mentioned have been out of development for some time so unless you got them from someone that has updated them they won't work.

In other words, time to find some new mods (though Sins plus has been combined into many other mods now).

I'm currently playing entrenchment, diplomacy makes my pc go crazy somehow. The weird thing is that before the upgrades i was playing just fine on entrenchment 1.5, now I cant, the game jsut freezes during the loading of the mod, i don't get a minidump nor a error, it just freezes.

More than likely its still the mods. Unless you found a version explicitly for Entrenchment 1.051, they probably won't work. You might have been playing an old version, and when you reinstalled impulse of course gave you the most recent version.

As a test, try getting one of the mods currently in development like DS or Maelstrom, and if it still doesn't work (just make sure its not an installation problem), then you might have a bizarre PC issue.

lol it works perfectly

btw awesome mod, pirates are soo overpowered, love it now they are a real treath
